PIPE-BEEN DING TO-0L.

Application filed April 9,

This invention relates to a pipe bending tool, and it is the principal object to provide a simple and. inexpensive pipe bending tool, but one which is strong and durable, yet cheap to manufacture.

Another object of my invention, is to provide a pipe bending tool, which will bend pipe at two different radii, as it is sometimes desirable to put a sharper bend at some por tion of the pipe.

My invention will be readily understood by reference to the attached drawing, in which Figure 1 is a substantially full size view of the pipe bending tool, in inverted position with a small section of pipe in the tube.

Figure 2 is a View of Figure 1, without the pipe, looking upon the right of Figure 1.

Figure 3 is a reverse view of Figure 1, but showing the pipe placed in the tool in a. position to secure the sharper bend on the pipe.

Figure 4 is aview of Figure 1 without the pipe looking from the left.

The pipe bending tool comprises a body portion 1, having a shank 2, the extremity of which is adapted to receive a handle as by means of the screw threads 3. The shank 2 is hollow or has a. hole 4 therethrough, the extremity of the hole at the threaded end of the shank being somewhat smaller diameter than at the end where the body and shank join, thus forming a shoulder 5, the object of which will. be later pointed out.

The body portion 1 has a hole or passage way 6 extending from end to end. The hole 6 is exposed on one side of the body portion 1 by a slot 7 which has a width-sulhcientto accommodate the passage of the pipe 14, which is to be bent, into the hole 6. The hole 4 merges into the hole 6, and at the junction a rounded portion 10 is provided on which the pipe 14- has a changing fulcrum.

During the bending operation a secon d fulcrum area. 11 is provided adjacent the outer rim 8, which rim .iscnlargcd and supported by the rib 13, to give strength to this portion of the tube. An additional strengthening rib 9 is also provided on the top portion of the tube. The body portion 1 is further strengthened where the holes 4 and 6 merge, as indicated by the rim 12, and where the rim 12 merges into the shank 2, the outer edge of the opening into the shank hole 4 is flared or rounded at 15 to provide a changing fulcrum for the pipe to be bent, by use of 1927. Serial No. 182,269.

15, at which time that surface acts as the fulcrum and continues so to act until the bend is completed, and due to the rolling or changing fulcrums the pipe is not kinked.

When it is desired to get a sharper bend than can be obtained by bending the pipe in the manner illustrated in Figure 1, the end of the pipeis inserted into the hole 4. The handle of the tool is then moved in the direction of the arrow Fig. 3, it being understood that the free end of the pipe is held in any desired manner, and the pipe is then bent over the rounded surface 15. c

It will be understood that the general contour of this tool may be varied without departing from thespirit of the invention, and the scope of the appended claims.

Having thus described my invention, what I claim is:

1. A pipe bending tool comprising: a body having a hollow shank extending therefrom. said shank adapted to have a handle attached thereto, said body having a hole extending from end to end therethrough and a. slot in one side of the body exposing the hole and having a. width .suflicient to receive into the hole, the pipe to be bent, said hole having at least a part of its formed surface curved so as to provide a changing fulcrum, said body at opposite ends of said hole having reinforced rims and strengthening ribs and the hole entrances flared to provide a second curved fulcrum area for the pipe as it is bent.

2. A pipe bending tool con'iprising: a body and a shank extending therefrom, said shank having means for attaching a handle thereto, said body having a hole extending from end to end therethrough and a slot in one side of the body exposing the hole and having a width sufficient to receive into the hole the pipe to be bent, said shank having a pipe receiving hole therein opening into the first mentioned hole adjacent one end thereof, the end entrances to said first mentioned hole and from said hole into the hole in the shank, being flared to provide a changing fulcrum for the pipe to be bent by use of either hole.

3. A pipe bending tool comprising: a body and a shank extending therefrom, said shank having means for attaching a handle thereto, said body having a hole extending from end to end therethrough and a slot in one side of the body exposing the hole and having a width sufiicient to receive into the hole the pipe to be bent, said shank having a pipe receiving hole therein opening into the first mentioned hole adjacent one end thereof, said body at opposite ends of the first mentioned hole having reinforced rims and strengthening ribs, the entrances to said first mentioned hole and from it into the hole in the shank, being flared to provide a changing fulcrum for the pipe to be bent by use of either hole.

at. A pipe bending tool comprising: a body and a shank extending therefrom, said shank having means for attaching a handle thereto, said body having a hole extending from end to end therethrough and a slot in one side of the body exposing the hole and having a width sufficient to receive into the hole the pipe to be bent, said shank having a pipe receiving hole therein opening into the first mentioned hole adjacent one end, said body at opposite ends of the first mentioned hole having reinforced rims and strengthening ribs, the outer edge of the opening into the shank hole being flared to provide a changing fulcrum for the pipe to be bent by use of the shank hole, said flared portion also acting as a second fulcrum when a pipe is bent by use of the first mentioned hole.

5. A tool for making in pipe, bends of two radii comprising: a body and a shank extending therefrom and having means for attaching a handle thereto, means for bending a pipe to one radius consisting of a hole extending from end to end therethrough in the body and a slot in one side of the body exposing the hole and having a width :suffi cient to receive into the hole the pipe to be bent, means for bending a pipe to another radius, consisting of a hole in the shank to receive the pipe, said shank hole being positioned adjacent one end of said body hole and the entrance thereto as well as the entrances to the body hole being flared as and for the purpose described. V

6. A pipe bending tool comprising: a hollow body having a hollow shank, said shank 7. A pipe bending tool comprising: a body portion and a shank extending therefrom, said shank having means for attaching a handlethereto, said body having a hole extending from end to end therethrough and a slot in one side of the body, exposing the hole and having width sufficient to receive intothe hole a pipe to be bent, said shank having a pipe receiving hole therein, opening into the first mentioned hole adjacent one end thereof, said body portion Where said holes come together being curved to provide a changing fulcrum for the pipe to be bent in the first mentioned hole, said shank hole opposite said rounded portion, being flared and rounded to provide a second fulcrum for a pipe positioned in the shank hole.

8. A pipe bender for bending pipe on two different radii comprising: a body part having a hole extending from end to end there through and a slot opening into the hole whereby the pipe may be passed into the hole through the slot, spaced fulcrum points over which the pipe is bent in said hole, a shank having a bore to receive an end of the pipe, the surfaces at the entrance to said bore forming a fulcrum over which the pipe may be bent and means for attaching to the shank an operating lever.

In testimony whereof, I afiix my signatura LEWIS H. CHURCH.
